  • VAAI and 3PAR

    We recently purchased some 3par storage and I did some migrations which were a lot slower than I had anticipated.

    Cloning a 150Gb server took about 25 minutes which translates to about 1Gb transfer, which sounds like it was not using VAAI but just using the hosts (which are connected to the SAN using 1Gb connections right now), the 3par has a 12Gb backplane.

    I read that 3par doesnt require a plugin, but uses the native T10 plugin. I am not sure if this plugin should show up in my vaai plugins or not, i dont see it there if it should...any help on getting VAAI to work on my SAN would be greatly appreciated

    I am using ESXi 6

    [root] ls | grep vaaip
    vmw_vaaip_cx
    vmw_vaaip_emc
    vmw_vaaip_eql
    vmw_vaaip_hds
    vmw_vaaip_lhn
    vmw_vaaip_mask
    vmw_vaaip_netapp
    vmw_vaaip_symm

    Running this command i see that Attached filter is blank..
